I do before I scheduled an installation..

I no dey like burn my tfare and I don't achieve result most especially when the job has been contracted to me

jonescosmos:
Because your Lithium battery pack needs to sense battery voltage before starting to charge, It can't help you when it sees 0V from the battery cells (0v Because your BMS has shut you off due to over DOD).

So, to wake up your Battery Pack, You need to Jump start the battery just like you do to your car. But bear in mind that you have a 24v battery pack.
Get a 24V external Battery Charger or An Adjustable DC Power Supply or even 2pcs of 12v Batteries that are charged up, Set the readings to about 27V 10A, Hook up the terminals Negative to Negative and Positive to Positive Terminals of the Charger and Battery respectively.

If your BMS is inbuilt you might need to open the Battery Box because the terminals you have access to outside the box are P- and B+, and you need to hook up your external DC power supply to B- and B+.

Once you do this and certisfying other Input conditions from your Inverter, Mains and Solar Panel sources, etc, your Battery should resume charging, then unhook the external power sources you applied earlier.

If this did not help, then there might have been a fault in your BMS.

I hope this helps. Cheers

Thank you chief

BRIGHTSOLAR:
Use Jump start method

Thank you chief

Please I need suggestions and opinion.

I have this 24v 5.12kw blue carbon lithium battery, that has been drained. The problem now is it has refused to come up.

I have tried using nepa to charge via the inverter , it not waking up, the solar panels too is not working as well...

How do I solve this problem?
Am thing of using an external 24v automatic low voltage disconnect switch to prevent further occurrence in the future, but I have no idea if such system is available.

Beside the inverter is a transformer based hybrid inverter with 100mppt controller.

I can't send image Now because of nairaland palava.

Senior men please come to my aid

I have got some fairly used solar panels for sale at sweet rate.

190 Mono
250 Mono and poly

Jesus thought his disciples to love their brothers in faith, friends, neighbours and enemies. We are to even pray for our enemies.
It was also repeatedly in the NT that we should take vengeance into our hand that we should leave it for God Almighty who will avenge for us.

So what a true Christian can do during violence and attack is to run. If it's a situation where it's impossible to run, then we can only depend on Jehovah God for a miraculous protection.

Shalom!

Why Peter carry knife dey follow Jesus up and down...

A little touch of violence is what is required.... To prevail in some instances

Leave JW people alone.....
It's their doctrine let them face it...

My only pain be say JW dey get some fine bannis whey dey enter my eyes , but they tend to be hell bent on their doctrine unless they are prepared to be dis-fellowshiped.

That aside, JW don't vote,they claim they don't believe in constituted authority, but how come elders exist in the Kingdom Hall (this is not a problem self).

The one that pains me is that they can't join force/ police because it's a form of constituted authority.

But yet Una dey go police station go report theft cases and call police when they are about to be robbed.....

You mean other people children are fit to die (at some point Putin prosecuted JW, I was not in support, but after critical thinking I didn't blame him at all).

Aside this JW are lovely people, leave their women/marriage for them...

Please I need urgent advice, because the money fit go down if I no invest!

Look for a way to hedge the money against inflation.

For business, look toward waste, energy , food

I have been having some issues in my room, I live with my mum and sister , it's a 3 bedroom flat, we pay 1.4m yearly and we've paid 3 times, last payment was in may.

My landlord increased the pressure point of our water in the compound and now water gas been leaking, pipes got burst in the wall and water has been coming out from walls and pop, I started complaining last month but they didn't do anything about it, it got to a point when the water was too much in my room, I wanted to get my landlords attention so I had to spoil our pumping machine and I brought out all the dirts in our dustbin, I acknowledge my mistakes but it was out of anger.

My landlord confronts me and we got into an argument and we insulted each other, I know i was wrong but if I didn't spoil that pumping machine, the landlord wouldn't have called plumber to repair the issues I was having in my room, I even discovered that i wasn't the only one experiencing such thing, my neighbors too were also having that same issues.

According to my landlord, he said he's not the one collecting money from us, we paid money to agent and if we have any issues we should contact the agent, this particular agent is his elder brother but this my landlord is living in our compound with us, though he has numerous houses.

Now my landlord said he doesn't want to see me again in his compound and has threatened my mum with quit notice, he said it's either I leave the house or my family would leave , he instructed the gateman not to open gate for me again or else he'll sack him. My fellow nairalanders I really need your help, how will I go about this?

Modified; The landlord threatened to call police if he ever sees me in his compound, he said he'll win me in court and it's malicious damage to his property, mind you, there's no evidence that I committed the offence, our gateman was the only eye witness.

Hope you are not owing?
Let your landlord take u to court....

If he gives you quit notice, he has to give you 6months to relocate this is if you are a yearly tenant.

Am still serving. Yes I’ve learnt barbing, I can handle dey-cleaning works as well

Open shop na....
Or start home service...

jawalis:
Life generally. I have graduated from the Uni since October last year and nothing seems coming forth. I struggled so hard to see myself through my seasons in the university and now I’m emotionally drained. No job, I don’t keep friends, no relative is checking up and I’m gradually loosing my mind. Life indeed is not fair.

Omo Kia....
Are you done with service?
Do you have any skill/hand work

Please how do we define "at a good price " on this thread ...
I just dey see at a good price up and Down

psucc:
That's on a very high side. I need something around ₦100k highest.

u cant get 3hrs on that load.

forsaleitem:
Thank you boss

Everything now works very fine

Battery got fully charged before 11am most time

Your welcome chief

forsaleitem:
2 X 180 watts panel = 90k for 2

100ah battery = 72k

1kv inverter = sachet cheaper but you can get reasonable ones like famicare or yohako (cost around 70k)

30a Charge controller = 11k

270k will do you

This would not last up to 3hrs-5hrs he mentioned.

psucc:
Good afternoon Sir,
Please I am in a srict budget. I need a system that will charge my laptop 90w (preferably, in the daytime), then tv(dell monitor), at least 5 lighting points (will change all bulbs to 5w) and decoder.
All items for at least 3-5hours in the evening.
Fan can wait.
My budget is very low.like how much will that take

Depending on your location, your budget should be around 470k upward.

This will get you something ideal.
A 200A battery 12v
Inverter and controller
Wire and accessories for the installation.

forsaleitem:
I've changed to parallel and positive changes noticed

Now, one more request

I watched the battery reach full today but I used it to some extent till it return to 3 battery bar and continue charging

3 bar remained but I switched off the inverter to enable battery continue to charge from around 3pm till evening but to my surprise, when the battery stopped charging it only shows 2bar whereas the continuation of charging showed 3 bar

Does that mean something discharge the battery?

I noticed reduction in voltage too because when the battery still under charge, it shows 12.6 as battery voltage and 12.7 as panel voltage going into the battery but when the panel stopped charging, the voltage showed 12.4v

I will need your input as regard this if it's normal or something is wrong somewhere

Thanks

This is quite normal.
For batteries to charge, u need a voltage higher than the batteries voltage, so I can attribute it to the extra voltage from solar panel.

Please try to charge the batteries full before using them after the previous incident.

That aside, weather has been bad for sometime now, for the first time my 12v system off on me....

Good job you are doing keep it up

forsaleitem:
Thanks
Panel Connections: I connected it myself and I watched it on YouTube

Negative on panel 1 connected to positive on panel 2

While we connect wire from charge controller accordingly i.e negative from charge controller to negative on panel 2, positive from charge controller to positive on panel 1

Also, voltage seen on charge controller varies from 10 - 11v around 7am till something 9. From 9am, it's always above 12.4 that it shows

Thank you

You DIY nice.
However your connection seem to be the problem.

Please go back and reconfigure it.
+ve of panel 1 to +ve of panel 2 and vice versa.

While doing this, please try to measure the voltage of the panels individually.

forsaleitem:
2 X 180w wired in series (I suspect the panel will be 150w because its China made)

100ah battery

30a pwm charge controller

1kv inverter

On first day, battery charged to full within 2hours because it already has 3bar from factory

Day 2: Battery charged full

From day 3, battery never charge to full capacity as it stopped mostly in 3 bar

Should I add 1 more solar panel to boost the charging or I should change the pwm controller to mppt? I can add more solar panel & change the pwm controller to mppt but I need your suggestion so I know the one I will do

Note: I normally put on 130watts power from 7pm till 10pm & only 20watts from 10pm till 7am each day

Thanks

I can't use the bars to tell what's happening.
The voltage will make it easier.

How did u know the connection of the solar panels.
